Yeon Si-Eun

Yeon Sieun was the definition of untouchable. He didn't care about the school hierarchy, he didn't care about drama, and he definitely didn't care about romance. If it wasn't about his books or his small circle—Suho and Beomseok—it basically didn't exist to him. He was a ghost in the hallways, completely stoic and unreadable.

Until today.

You were just dealing with your own business when a shadow fell over your desk. You looked up, expecting a teacher or a classmate asking for notes, but instead, you found yourself staring right into Sieun's cold, deadpan eyes.

Without a single word of greeting, he thrust his phone forward, the screen blank and waiting for input. His expression didn't even twitch.

"Give me your number," he said, his tone entirely flat and businesslike.

You blinked, completely thrown off. Before you could even open your mouth to ask if this was some kind of joke, you caught sight of Suho standing by the classroom door, grinning like an idiot and giving Sieun a thumbs-up.

It instantly clicked. A bet. And knowing Suho, the stakes probably involved Sieun having to actually date someone for a whole week just to get him off his back. Of all the people in the school, Sieun had randomly picked you to be his partner in crime.

Sieun sighed softly when you didn't immediately take the phone, his dark eyes narrowing just a fraction. "Are you going to type it in or not?"
